Sentry SDK Java 不适用于 aws lambda

Question

I am trying to use sentry in java based aws lambda. I am trying to used sentry v3.1.1 in a simple lambda which captures exception as below. The problem is

• it works fine when run locally using main method , and event appears on sentry issues ui
• but it doesn't work when invoked in as aws lambda and event never appears on sentry ui.

SentryLambda.java

package playground.demo;

import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import io.sentry.Sentry;

public class SentryLambda implements RequestHandler<String, String> {

  @Override
  public String handleRequest(String input, Context context) {
    Sentry.init();
    Sentry.captureException(new Exception("Test Sentry"));
    return "Returned "  + input;
  }

  public static void main(String[] args) {
    SentryLambda sentryLambda = new SentryLambda();
    sentryLambda.handleRequest("Requested String", null);
  }

}

I also tried creating aws lambda with vpc config and internet access but did not succeed Can anyone please guide me why it's not working and how can I make it work?

PS Before all this, I tried working with sentry-log4j2 and sentry-logback , and eventually reached to simple sentry-java . They all work locally but fail on aws lambda

[Update: Nov 02, 2020]

As @Manoel suggested to set debug flag, here's the updated code and logs.

SentryLambda.java

    ...
    Sentry.init(options -> {
      options.setDebug(true);
      options.setDsn("...");
      options.setEnvironment("development");
      options.setRelease("0.0.1-SNAPSHOT");
    });
    ...

Answer 1

could you enable the debug mode and copy-paste the logs?

Sentry.init(options -> {
  options.setDebug(true);
});
